Question

find the mean of squares of first five whole numbers

Answer 1

Hey mate.
Here is your answer-

'Mean' is an another word for 'Average'

First five whole numbers and their square=

${0}^{2} = \: 0 \\ {1}^{2} = \: 1 \\ {2}^{2} = \: 4 \\ {3}^{2} = \: 9 \\ {4}^{2} = \: 16$

Mean (average) =

$\frac{sum \: of \: observations}{total \: number \: of \: observations} \\ = \: \frac{0 + 1 + 4 + 9 + 16}{5} \\ = \: \frac{30}{5} \\ = \: 6 \: answer$

Therefore, mean of square of first five whole numbers is 6.

Hope it helps!!!!!
